Values are presented as mean±standard deviation. The ADI-R score statistics are for the 54 individuals in the ASD group for whom scores were recorded. ADI-R_ Social total: reciprocal social interaction subscore total for ADI-R; ADI-R_Verbal total: abnormalities in communication subscore total for ADI-R; ADI-R_RRB total: restricted, repetitive, and stereotyped patterns of behavior subscore total for ADI-R; ADI-R_Onset total: abnormality of development evident at or before 36 months subscore total for ADIR.

^*FIQ is only a group comparison of the other two sample sets because there is no FIQ value for the sample from the University of Leuven sample;

^†independent sample t-test;

^‡chi-square test.
